300BLK fans have been really quiet since this was launched.

I think Winchester really dropped the ball on advertising this as "357 Supermagnum Rimless". It is a solid competitor and in a couple of respects superior to 300 BLK, sort of like an American 9x39. Even without a fast twist you can shoot bullets just as heavy as the 300BLK while being more efficient in short barrels and still using common caliber bullets.

        >i have legitimately been wanting something like 357-level in the .30 carbine size for forever
        Doesn't .30 carbine already have pretty comparable ballistics to .357?

        might have been true for ww2-era 357s but the 30carbine is like 50% lighter bullet weight so fast and flat.

        yeah, the low sectional density bullets work great in short barrels. the powder burn is pretty much the same as .300BO, because they use the same powders.

      Not considerable gains, but you’re right, the 350 legend is still gaining nontrivial velocity in barrels longer than 9”. Although the bullet is wider, so is the case, and height of the propellant column is taller. I think it’s got proportionally (to caliber) more powder than 300 blackout. Dunno exact numbers, but it is like an 1800ft*lb cartridge.

    That's the truth of the matter.
    You have a redneck hunting cope cartridge that doesn't supress as easily or as well as 300blk, isn't nearly as reliable across barrel lengths and bullet weights, can't match capacity, doesn't feed as well and is more prone to malfunction, and doesn't have the power of other, better straight wall rounds for hunting, like 450 bushmaster.

    I know shitposting about calibers is tried and true PrepHole condition but it's still retarded. 300bo is about practicality not ideals.
    1. Uses standard 30cal cans which have massive options and everyone has already. There is zero point in even talking about quiet guns if you don't have a suppressor, and they're a pain in the dick to get (t. in line for next one, expecting approval from atfdaddy no earlier than next spring). It's a huge practical advantage to have a can that can be used for 300bo/308/300wm and even 6.5.

    2. 300bo subs are reasonably priced and widely available off the shelf. 220gr subs start at around 64cpr. If you reload there are better options than 350l too though your call in that case, but that's nothing about regular popularity. 350l factory 255gr starts at over 100cpr.

        >i wonder if 9mm smg suppressors can handle 350l
        With a heavy duty steel or inconel baffle system a can would survive just fine, pistol cans would do better than an "SMG" one actually in theory since pressure drops with barrel length, and people do use handgun cans with subsonic loads sometimes. But anything designed for 9mm would be much louder, out a short barrel we're talking a pretty massive pressure differential. 350l is a typical rifle 55k psi, while even +P 9mm is 38.5k. 9mm SMGs like an MP5 are ~9" barrels, and generally fall into the same 8-11" range that are typically popular for SBRs. Pressure drops with barrel length and burn so of course with a long barrel you could get 350l down but if we're comparing like and like that'd be a much, much bigger blast than even the Hispaniciest bubba 9mm ever.

                nta but while no a decent 9mm can isn't going to break or anything from 350l out a 16" barrel even with supers the suppression performance isn't great either vs 300bo with a quality 308 can even with a much shorter barrel. FWIW I'm not shitting on you liking it, it's not like it's some snowflake meme caliber and people who know what they're doing and shoot can use anything they want as far as I'm concerned.

                That said on a personal level it's an odd duck to me short of being in a straight wall state. For factory <225yd (which is 99% of non-range use around here), 300bo is plenty of energy, significantly cheaper, has more load coverage, more gun choice, and better suppression and SBR characteristics. It's a decent jack of all trades compromise round.

                For those of us who reload there are tons of way way more interesting rounds IMO at all distances than EITHER of them. For subs there is even awesome stuff like .510whisper which can go astonishing distances and actually outperform many supers at enough distance. But also more general options like 375.

                Again if 350 works for you that's fine, but just hasn't ever gripped me.

                the "300BO subs are actually quieter" is a retarded because the difference isn't perceptible, it's only measurable. what is important about the caliber is that it has subsonics and that they are heavy. This is why nobody is like

                yeah, they don't work in long guns, .357 mag, for example is garbage out of anything longer than 6", the bullets turn to marshmallows because I'm a dumb moron like you. there definitely aren't literal commercial .357 mag loadings that dunk on .300BO because it's shit for tactikiddies and paper punchers.
                so what we've established is that there are every kind of desirable bullet available, plus a hilarious number of cheap options for loading .350 legend.
                that seems like a good thing, but I don't have any birth defects because my mom didn't smoke cracks while pregnant.

                At least you admit it
                >Yeah it’s really easy to reload subs and cast lead projectiles are cheap

                >recommend 180gr .357 bullets
                For the 3rd time, have fun neutering your subsonics. Do you not understand why a lighter, fatter bullet, at the same speed is worse?

              a whopping 15 extra grains per shot is a really lousy trade for less reliability, 10 less rounds per mag, scarce suppressor selection, and possibly worse BC
              265 grain 300blk bullets goes for as low as 23 cpr

        >Yeah it’s really easy to reload subs and cast lead projectiles are cheap. You can even get molds and powder coat and get even cheaper (you do need to shoot a lot of offset the equipment cost though). Plus your normal bullet selection is better because there is a million .30 cal bullets.
        If you reload and don't live in a straight wall state, seriously, why would you use 350l vs 375 raptor or something like that? The whole point of reloading is to escape most of the constraints of mass manufacturing because your costs get pretty flat so long as you don't need to get too crazy on the brass side. You can have the weirdest most niche fully custom load in the world and it'll still cost brass+bullet+powder+primer. Almost 100% of the caliber bullshit goes away when you reload, you just do what you like and customize exactly to your needs/desires. That's why it's awesome!

        But objectively speaking anon we both know the overwhelming super majority of gun owners don't reload, they buy off the shelf. That's what the caliber war shit is always about. Reloading is meaningless in these discussions, only whatever ammoseek or god help us rando LGS have. Optimal doesn't come into it unless the result is so superior it achieves critical mass.

          350l really excels in short range supersonic, not subsonic like op is implying
          out of a 10" barrel, it gets higher muzzle energy than m855a1 out of 20"

    .350 Legend is a good cartridge that was hampered by horseshit from the start.
    >No parent cartridge
    >Ambiguous bullet diameter from the start, somehow incompatible with .358 bullets except when it's not and standardizing in .355's
    >Being just weird enough to not quite feed from unmodified .223 magazines
    >Being marketed as a better .30-30 with cherry picked advertising numbers
    >Being named fucking "legend"

    That said, by virtue of it being a medium bore intermediate cartridge it is superior to .300 blk'd in all but recoil.
